ADJUSTABLE SUPPORTING- DEVICE.

Application filed March 17, 1924. Serial No. 699,888.

To all whom 2'25 may concern.

Be it known that l, Onor P. Wonsrnan, a subject of the King of Norway, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Adjustable Supporting Devices, of which the following is a specification.

This invention relates to builders equipment, and the main object is to provide a novel design of telescoping members adapted to be used temporarily in the construction of buildings and other places where temporary supports such as scaffolds, horses, concrete form braces and the like are usually employed. Such supports are commonly made of wood and after the structure is complete are taken down and either de stroyed or removed to other places and again set up. As the lumber is usually cut to meet the particular requiren'ients on each job, however, and when being removed is often pounded or twisted to pieces, a great less frequently results, and it is my purpose to eliminate, or at least greatly reduce this loss by substituting adjustable tubular sup ports of metal, which will last a long time and which can be readily adjusted to suit the various circumstances met with. The invention is illustrated in the accompanying drawings, wherein:

Fig. 1 is an elevation of an adjustable column having a head support, embodying my invention.

Fig. 9. is an enlarged sectional elevation on the line 2-2 in Fig. 1.

F 8 is an enlarged section on the line 33 in Fig. 1.

Referring to the drawings more particularly and by reference characters A designates a column or post con lsting of interslidable or telescoping sections 13 and 14, which are provided with holes or slots 16 adapted to register so as to detachably receive securing devices such as nails 17. A cross truss B is arranged at the upper end of the column and is adjustably secured thereto by pins or nails, in the same manner as the telescoping column sections are secured together. This truss B is made of a single piece of heavy sheet metal bent to a substantially U-shaped form, and inverted, its edges inclining from its outer ends down toward the column. A block or piece of timber C may be inserted between the column end and the truss, and clamped between the two, and thus completes a brace which is particularly adapted for use in supporting concrete floor slabs when a building is under construction, or for any other similar overhead supporting purpose. The member B is braced against a tilting movement on the column by a set of flanges 19 which are bent in from the body of the member so as to meet, the edges being welded together a at 20, thus forming a rigid tubular channel in which the section 18 is adjustably secured. The block C may of course be substituted by longitudinal tubular members, such as 14:, if so desired.

It is understood that suitable modifications may be made in the general design and structural details of the invention as herein disclosed, provided, however, that such modifications come within the spirit and scope of the appended claims. Having now therefore fully illustrated and described my invention, what li claim to be new and desire to protect by United States Letters Patent is:

1. A column having perforations therein, a head member consisting of an integrally formed face plate slid-ably engaging the front and back of the column and having perforations adapted to register with the perforations in the column and be locked therewith by pins, flanges bent in from said face plate toward the sides of the column to form a channel therefor.

2. A. truss head consisting of a pair of spaced vertical plate like members having inwardly bent portions forming therewith a socket for the reception, of the upper end of a column, said plate like members connected by a transverse portion at their up per edges so as to form an inverted channel for receiving a horizontal head member carried by the column.

In testimony whereof I affiX my signature.
